IMPROVEMENT IN SEED-SOWEB/AND HARROW.

fittiz Stlgzhule refemh it it these islets fitted animating get at tip same TO ALL WHOMI'IT MAY OONGERN:

' Be. it known that I, ANDREW WALKER, of Claremont, in the county of Sullivan, and State of New Hampshire, have inventedcertain Improvements in Seed-Sewers and Harrows; and I do hereby declare that the f0llowing is a full and exact description thereof, which'will enable those skilled in the art to make and use the same, reference being bad to the accompanying drawings, and letters of reference marked thereon, in which--- Figure I is,a side view of my said seed-planter and-barrow, showing the arrangement'of its parts, the frame A, seed-box B, ratchet-lever C, pivoted to the main ca'rrying-wheel axle at D, the barrow G, pivoted or attached to the rear end of lever at E, the sectional gears F ofdriving-wheel, shown'by dotted circular line, gearing into the small gear-wheel G, to rotate the barrow G. The sectional circular gears, shown by the section F, and the circular dotted line,are attached to the main wheel'by certain well-known attachments not necessary to specify,

asthey are in common use; H is a smallgear-wheel that rotates the, fiuted roller or seed-distributer, as shown in Fig. III by d, which is geared into the driving-wheel of which F is a section. I is agear-wheel, worked by the lever K, and gears into'thc ratchet of the ratchet-lever G, stopped at any point of adjustment by the springstop a, thus allowing the harrow to be set to any depth i Figure II shewsthe ratchet-lever C pivoted to the axle of the wheel D, the scgmcntary ratchet in front gearing into the gauge-ratchet wheel I, and showing the journal-box E at rear end, with the journal of the harrow passing through the box.

Figure III shows a section of the seed-box, showing the valves Z 12-, thegaug'e-rod c, and .the fluted roller cl;

The improvements herein referred to consist of the combination of a seed-sewer and harrow, the harrow being attached to a lever arranged so as to raise or lower it. I am well aware that rotary barrows have been in use. My improvement consists of a harrow attached to the rear end of a lever pivoted to the main axle of the carrying-wheels, and geared to the driving-wheels by small gear-wheels, which cause it to revolve, alsov the plan of raising and lowering the harrow by the use of a lever-attachment. By lowering the lever, the harrow will merely scratch the ground, useful in that position for covering small seeds or the mixing of plaster or other manures with the soil. I By raising or pushing the lever forward, it sets in deeper. Harrows that are merelyrotated by dragging them over the ground, make depressions in thesurface to correspond to the teeth or arms. All the disturbance of the surface is in that case made by' the arms prying themselves out of the ground, and not raising the surface enough to cover tlie seed. Harrows worked by gears tear up and agitate the surface, so as to completely cover the seed, and mix the manurcs sown. My improvement for distributing the seed is such that by raising or shortening the gauge-rod c, in Fig. III, I can control the distribution of the quantity of the seed.

The following is a'description of the construction and operation of my said improvements:

Fig. I. B is a seed-box, attached to the frame A. O isa lever, pivoted to the main axl'e at D. At the rear end of lever O is the point of attachment for harrew, shown at E, the harrow rot-atedby the gear-wheel G geared into the circular wheel, of which..a section is shown at F, the gauge-ratchet wheelgearing into a circular section of ratchet-lever 0. Dis the journal or axle of carrying-wheel. H is thegear-wheel, to rotate the fluted seed-roller, shown at d, Fig. III 0 is a geared circular ratchet, to catch or hold the stop a, attached to the lever K. I

Fig. IIshows the ratchet-lever C, carrying wheel-journal D,journal of barrow E, gauge-gear wheel I circular ratchet a, lever K, with its adjustable stop a; I I v Fig. III shows the interior of the seed-box B, the valves 6 b, gauge-rod c. The seed is distributed by raising or shortening the rod c by the nut at its top. The valve 6 is raised enough by shortening the rod 0 to allow-a certainamount of seed to pass over orin the flutes of the roller d. The valve 17 is to prevent any. seed passing through between-the wall of the seed-box and the fluted roller 01.;

What I claim as my invention, and desire to secure by Letters Patent, is i 1. The ratchet-lever G, in combination with the harrow G, the geabgauge wheel I,-1ev er K, and circular ratchet o, with the spring-stop a in lever K.

2. The valves 6 b, attached to the seed-box B, and gauge-rod e, in combination with the fluted rollcr d, the whole combined, arranged, and used as and for thepurpose set forth. i
